Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of Stillwater Mining (NYSE: SWC) jumped 23% today after the company said it found more shiny metals than expected when it reported earnings.

So what: Production at two Montana mines grew 6% to 130,000 ounces helping revenue rise 77% to $253.7 million for the quarter. That drove earnings dramatically higher to $40.7 million, or $0.37 per share, higher than the $0.33 analysts were expecting.

Now what: High palladium and platinum prices helped drive results, but production was also better than expected. Management did point out that prices fell during the quarter because of the turmoil in Europe, so it might not be reasonable to expect another blowout like this next quarter. Investors should be pleased with the results, but I'm not seeing a need to run out and buy shares unless production is increased in the future.
